Hi. I'm converting my own web browser use WPF from Windows XP to Windows 7.
when I test on Windows XP, It has no error and exceptions.
But I convert and test on Windows 7 with Multi-touch Library, My Browser occurred unhandled exception.
Source: PresentationCore
Message: An unspecified error occurred on the render thread.
StackTrace:

InnerException: null
I want to know where the bug occurred. That Trace Message are garbage information for me.
I already googling to know that message, but i never found any information.
How do I get exactly function where the bug occurred? please tell me something.
